Explanation:

A flowchart is a graphical representation of a process or algorithm, which is commonly used in software development. It makes it easier to understand the workflow of a program or a process. Each step in a flowchart is represented by a shape, and connectors are used to link these shapes together. The symbol used to represent a connector in a flowchart is a circle.

Why is a Circle used as a Connector Symbol?

The circle symbol is used as a connector in a flowchart because it represents the start or end of a process. A flowchart typically starts with a circle, which is used to indicate the beginning of the process. The circle is also used to indicate the end of the process. This makes it easier to understand the flow of the process, and to identify where it starts and ends.

Other Symbols Used in Flowcharts:

In addition to the circle symbol, there are several other symbols that are commonly used in flowcharts. These include:

- Rectangle: Used to represent a process or a task.
- Diamond: Used to represent a decision point, where the flow of the process can go in two or more directions.
- Oval: Used to represent the start or end of a process.
- Arrows: Used to indicate the direction of flow between shapes.

Conclusion:

In conclusion, a circle is used as a connector symbol in a flowchart because it represents the start or end of a process. It is important to understand the different symbols used in flowcharts in order to create effective and easy-to-understand diagrams.
